FujiFilm FinePix S1 Pro Review: 14. Image Quality: Digital Photography Review

Resolution Charts

Shots here are of the PIMA/ISO 12233 standard resolution test chart (more available for comparison in our cameras database). How to read the charts: All values are 1/100 th lines/picture height. So the "10" value equates to 1000 lines/picture height.

"What, you're comparing it to the Coolpix 990?", I hear you cry. Well, my logic is that the S1 Pro should be much better because of FujiFilm's SuperCCD technology. Pixel counts are similar (Nikon Coolpix 990 3.14 million effective, FujiFilm S1 Pro 3.07 million effective). For reference we've shot the resolution chart at both 3040 x 2016 and 2304 x 1536.

FujiFilm S1 Pro (@ 3040 x 2016)	Nikon Coolpix 990 (@ 2048 x 1536)

FujiFilm S1 Pro (@ 2304 x 1536)	Nikon Coolpix 990 (@ 2048 x 1536)

Well there you are, interestingly the S1 Pro shows much higher resolution than the Coolpix 990 (probably not just down to the CCD but also the lens) but has some strange artifacts (and moiré aliasing) visible in angular lines as blue or yellow artifacts - take a look also at fine detail in the images in the samples galleries and you'll see the same thing. A side effect of the SuperCCD's honeycomb design?

Measurable findings (three measurements taken for each camera):

Camera	Measurement	Absolute Res.	Extinction Res.
FujiFilm Finepix S1 Pro	Horiz LPH	1300	1450
	Vert LPH	1200	1400
	5^o Diagonal LPH *	1000	n/a
Nikon Coolpix 990	Horiz LPH	900	1300
	Vert LPH	900	1400
	5^o Diagonal LPH	900	n/a

* Visible moiré artifacts

Definition of terms:

LPH	Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)
5^o Diagonal	Lines set at 5^o diagonal
Absolute Resolution	Still defined detail (below Nyquist frequency*)
Extinction Resolution	Detail beyond camera's definition (becomes a solid gray alias)
n/a	Not Available (above the capability of the test chart)
n/v	Not Visible (not visible on test results)

* Nyquist frequency defined as the highest spatial frequency where the CCD can still faithfully record
image detail. Beyond the Nyquist frequency aliasing occurs
